Let
x-------> distance in the map in cm
y-------> actual distance in Km
we know that

so
--------> equation 
<u>Part 13)</u> find the actual distance corresponding to the scale map 
In this problem we have

Substitute the value of x in the equation
to find the actual distance

therefore
<u>the answer part 13) is</u>
the actual distance is 
<u>Part 14)</u> find the actual distance corresponding to the scale map 
In this problem we have

Substitute the value of x in the equation
to find the actual distance

therefore
<u>the answer part 14) is</u>
the actual distance is 
<u>Part 15)</u> find the actual distance corresponding to the scale map 
In this problem we have

Substitute the value of x in the equation
to find the actual distance

therefore
<u>the answer part 15) is</u>
the actual distance is 
<u>Part 16)</u> find the actual distance corresponding to the scale map 
In this problem we have

Substitute the value of x in the equation
to find the actual distance

therefore
<u>the answer part 16</u>
the actual distance is
